CVE-2015-0253: Apache HTTP Server

Medium severity, CVSS 5.0. EPSS: 13% chance of exploitation in the next 30 days.

The read_request_line function in server/protocol.c in the Apache HTTP Server 2.4.12 does not initialize the protocol structure member, which allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) by sending a request that lacks a method to an installation that enables the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI.

• Apple Mac OS X: version 10.10.4 only
• Apple Mac OS X Server: version 5.0.3 only
